ARCTIC Liquid Freezer III 240 A-RGB

Best Overall 240mm AIO Cooler

Specifications: Dimensions: 277 x 120 x 38mm | Fans: 2x ARCTIC P12 PWM PST A-RGB | Fan Speed: 200 – 1,800RPM | Socket Support: Intel: LGA 1700, AMD: AM4, AM5 | RGB: Yes 

Read Our ARCTIC Liquid Freezer III 240 White A-RGB Review

My first recommendation for the best 240mm AIO is the ARCTIC Liquid Freezer III 240 A-RGB. I have tested both the older Liquid Freezer II 240 and the latest Liquid Freezer III 240 on my i7-13700K, and the performance difference between them is day and night. Apart from the high-performance P12 PWM PST A-RGB fans, the main reason why this AIO performs so exceptionally well is due to the denser fin stacking, giving the radiator ~23% more surface area.

Of course, the 60mm VRM fan is a great add-on that made sure my overclocking adventures remained as stable as possible. Plus, the pre-routed cables mean very little cable clutter. The radiator and the baseplate are made using aluminum and copper, so there are no issues with the build quality, either. As for the design, there is an RGB pump cover and fans, but I would have liked to control the lighting of the two independently. Nevertheless, it has a sleek design that looks like a breath of fresh air from its predecessor. 

Here’s what I said about the ARCTIC Liquid Freezer III 240 A-RGB in my review:

I’ve been really impressed with the Arctic Liquid Freezer III 240 White ARGB. It’s clear they’ve made significant strides in design and performance, taking user feedback to heart. The fact that it fits major sockets, excels in heat dissipation and offers sleek cable management really stands out.

What Makes It The Best Overall 240mm AIO Cooler?

The main reason I’m recommending the ARCTIC Liquid Freezer III 240 over other coolers is that it is a complete package that does not compromise performance one bit. From the sleek pump design to the increased surface area on the radiator, ARCTIC has knocked it out of the park with the sheer amount of improvements in the Liquid Freezer III series. Plus, combined with the impressive pricing, there is no other option that I would call the best overall 240mm AIO.

EK Nucleus AIO CR240 Lux D-RGB

Best High Performance 240mm AIO Cooler

Specifications: Dimensions: 281 x 124 x 27mm | Fans: 2x EK-Loop FPT fans | Fan Speed: 550 – 2300 ± 10% RPM | Noise Level: 36dB(A) | Socket Support: Intel: LGA 1150, 1151, 1155, 1156, 1200, 2011, 2011-3, 2066, 1700 AMD: AM4, AM5 | RGB: No

Read Our EK Nucleus AIO CR240 Lux D-RGB Review

The EK Nucleus AIO CR240 Lux D-RGB is the best high performance 240mm AIO you can get right now. In all of my testing, it handled both high-end gaming and long stress tests without breaking a sweat. In fact, the AIO performed so incredibly well that it topped my 240mm AIO testing charts by a mile. It uses the EK-Loop FPT fans that offer exceptional static pressure (hence the name Full Pressure Technology). Plus, the pump can operate at speeds of 3100 ±10% RPM, which is very impressive.

Going over the build quality, I had no issues at all. The radiator, pump, and even the tubing are built from high-quality materials and are meant to last; being EK, I don’t expect anything less. I only wished that the tubes were longer than 370mm. That would have made installation even easier (not that it is difficult right now). On the upside, the fans can be daisy-chained to reduce cable management. As for the looks, the AIO offers a stealth black design with no flashy RGB – perfect for neutral or black builds.

Here’s how I summarised the cooler in my hands-on review:

The EK-Nucleus CR240 Dark is a sleek, high-performance 240mm liquid cooler without RGB, designed for Intel and AMD platforms. It features efficient cooling with a copper cold plate, EK-Loop FPT fans, and a simple cable management system.

What Makes It The Best High Performance 240mm AIO Cooler?

Apart from the stealthy looks, high build quality, and great value for money, what makes the EK Nucleus AIO CR240 Lux D-RGB the best high performance 240mm AIO is its cooling capabilities. The AIO really knocks high-stress loads out of the park, and you can easily push even the latest flagship CPUs to the limit with it.

ID-Cooling FrostFlow X 240

Best Budget 240mm AIO Cooler

Specifications: Dimensions: 276 x 120 x 27mm | Fans: 2x 120mm fans | Fan Speed: 700 – 1,800RPM | Noise Level: 18 – 35.2dB(A) | Socket Support: Intel: LGA 2066, 2011, 1700, 1200, 115X AMD: AM4, AM5 | RGB: Yes

The ID-Cooling FrostFlow X 240mm AIO cooler is one of my favorite budget CPU coolers because of its beautiful aesthetics and remarkable cooling performance, albeit unable to beat most of its competition. Starting from its build quality, you’ll see a copper baseplate and an aluminum radiator with an 18 FPI. Although the number is less than 20-21 in most AIO coolers, the cooling isn’t as compromised.

Regarding its performance, the ID-Cooling FrostFlow X 240 is decent for most use cases, but I don’t recommend it if you want to achieve high overclocks on a flagship processor. You’ll be fine on a mid-range CPU, though. Furthermore, I like the cooler’s looks, featuring a neat-black design and gorgeous LED lights all over the pump. My only issue is that the RGB lights could be slightly brighter. Other than that, it’s perfect for a budget AIO cooler, costing half the price of its competitors.

What Makes It The Best Budget 240mm AIO Cooler?

When talking about AIO coolers, you’ll first notice their thermal performance. Now, if a 240mm AIO cooler performs on the same level as a 360mm but comes at half the price, you’ll want it, right? That’s where the ID-Cooling FrostFlow X 240mm AIO cooler comes in. It provides decent performance, pleasing aesthetics, and excellent features while staying at a low price, making it the best budget 240mm AIO cooler.

Benchmarks Of The Best 240mm AIO Coolers

To make sure my recommended 240mm AIOs are truly the best in the market, my team and I tested several 240mm AIOs. Our testing methodology included stress testing the i7-13700K with a full 30-minute load on Cinebench with power limits removed. Basically, we pushed the AIOs to their limits. However, for gaming scenarios and most day-to-day use, you’ll not experience such high thermals unless you install the cooler incorrectly.

Why We Didn’t Go For These 240mm AIO Coolers

Our hardware experts have tested countless 240mm AIO coolers, but here are a few honorable mentions that didn’t make the cut for our list and why:

• NZXT Kraken Z53 RGB: A higher price for lower performance makes it a less viable purchase.
• DeepCool Castle 240EX: It has an older generation pump, making it less suitable for the latest high-end CPUs.
• EK AIO 240mm D-RGB: It has been discontinued and doesn’t support LGA 1700 right out of the box.

How We Picked & Selected These 240mm AIO Coolers

When it comes to choosing an AIO for your CPU, we always advise our users to consider all factors before making a decision. Choosing an AIO cooler can sometimes be difficult due to the variety of options available, but don’t worry; we’ve collected a list of buying recommendations to help you make an informed decision.

• Socket Compatibility: Every CPU has a different number of pins, meaning a different socket size. Before choosing a 240mm AIO, make sure it supports your CPU socket. Buying an AIO with the wrong CPU socket compatibility will not work. To check the socket compatibility options for your preferred cooler, visit the manufacturer’s site.
• TDP: Knowing your preferred AIO cooler’s Thermal Design Power is another important factor, as you don’t want the AIO’s TDP to be lower than the CPU’s. Otherwise, you won’t be able to cool your CPU correctly, leading to thermal throttling and lowering your PC’s performance.
• Noise Levels: Sometimes, some users prefer dead silent PCs; that is why we always say to make sure to do your research before purchasing a product with so many moving parts. AIO coolers contain fans and pumps that tend to make a lot of noise at times, and lowering RPM speeds reduces thermal performance, too.
• Aesthetics: In the end, you can always go for good looks. 240mm AIO coolers are available in countless shapes and designs, from the good-looking Corsair 240mm radiators to the decent and silent be quiet! You can always choose the AIO that best suits your personality.
